IMPROVEMENT IN SOLDRING- APPARATUS.

The Schedule referred to in these Letters Patent and making part ofthe same.

To all whom yit may concern:

Be it known that I, JACOB GULDEN, of Key Port, in the county of Monmouth and State of New Jersey, have invented a new and Improved Gan-soldering Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof',

which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification, in which- Fignre l represents a side elevation of my improved cau-soldering apparatus. v

Figure 2is aver-tical transverse section of the same, taken on the plane of the line x x, iig. l.

Figure 3 is a plan or top view of the same.

Similar letters of reference indicate corresponding parts. k This invention relates to a new apparatus for soldering the seams of sheet-metal cans, and consists in the use of .a tubular furnace, which is combined with sliding soldering-irons that workin the tubes for the purpose of being heated therein.

'lhe invention consists, also, in the application to the apparatus, of a set of springs for holding the cans on the blocks that are prepared for them on the sides of thefurnace.

A, in the drawing, represents a furnace of rectangular or other suitable form, supported on a frame, B, of suitable description.

. The4 furnace contains a grate, a, smoke-pipe b, and fire-deer e,in the ordinary manner. Through the furnace are fitted two, more or less, transverse pipes'O C, which are arranged above the nre-place, to be surrounded and thoroughly heated by the dames.

Through one open end of each pipe C, is inserted wit-hin thesame a sliding bar, D, made of metal.

The outer end of cach bar D carries a solderingron, E, and the handle :l for operating the same.

The heated pipes C serveto heat the bars D. and thereby the irons E.

F F are blocks secured to the sides of thc furnace, one under each iron E; These blocks are so shaped as to conform to the shape of thev cans to be soldered, which may be of cylindrical, prismatic, or other suitable form.

The can G is slipped upon thc block F, so that its long seam will be under the iron E. The seam before soldering is heid closed by means of a spring, H,

which is secured to thelside of the furnace, as yshown in fig. 1. E moved along the seam.

It will be seen that by this construction of apparatus the soldering process can -be carried on on each side of the furnace, and that, therefore, the heat of the furnace can be 4utilized for a suitable number of soldering-blocks.

Having "thus described my invention,

I elairn as new, and desire to secure by Lett-ers Patcntl 1. The furnace Aprovided with the open ended tubes G, forreceiving the. reciprocatin'g-shanks D of the-soldering irons, as set forth.

2. The springs H, combined with the blocks F, for the purpose of holding the can in position for soldering, as set forth. v
